I used a Revit 2011 model to create an ISM repository, which I subsequently used to create a RAM Concept model for slab design. After designing the slab in Concept, I was able to update the repository with the rebar information, with all of the rebar showing up as a property called "Rebars" in the "Properties" table for the slab. I can also view all of the rebar in 3D in the ISM viewer. However, when I try to update the Revit model from the repository, the the new slab does not have a property called "Rebars" when viewed in the Structural Synchronizer, and no rebar is created in the Revit model.
Is it possible to update a Revit model with rebar from an ISM repository? If so, how? Any direction would be much appreciated
